Use a map when you want to see patterns in your data by geography.
Your data asset must contain geographical data, such as countries, states, provinces, or continents.

To determine whether a column is mappable, Cognos Analytics analyzes a sample of 2000 values in the location column, looking for recognizable place names. If 80% or more are recognized as map values, Cognos Analytics produces a map.
For example, you have four countries in your location column: Brazil, China, India, and Russia. The typographical error for India means that only 75% of the values are recognizable place names and you will not see a map as a starting point. But if you have five countries and one has a typographical error in it, you see a map.
For example, this map visualization shows revenue by retailer country with the darker color indicating higher revenue.
